Abstract: A plurality of metallic nano-body groups that includes metallic nano-bodies which are a size smaller than the wavelength of incident light and are dispersed on a dielectric surface is arranged in one direction at a pitch that resonates with the incident light. A long piece extends on the dielectric surface between adjacent metallic nano-body groups. The long piece is formed of a material having no free electron that performs resonance oscillation with the incident light. Localized surface plasmon resonance occurs in the metallic nano-body by the action of the incident light. Propagating surface plasmon resonance occurs by the action of the pitch. The propagating surface plasmon resonance is combined with the localized surface plasmon resonance. A so-called hybrid mode is established. The long piece is helpful in the establishment of the pitch.

Abstract: An optical device includes a first protrusion group in which protrusions protruding from a conductor surface of a substrate are arranged in a first direction with a first period, a dielectric layer that covers the conductor surface and the first protrusion group, and a second protrusion group in which metal nanoparticles are arranged on the dielectric layer in the first direction with a second period different from the first period. When one of the first period and the second period is defined as Px1, the other of the first period and the second period is defined as Px2, and the wavelength of irradiation light is defined as λ, λ>Px1>Px2 and 0
